  2. 1. Realise the Potential! : Cost Effective and Energy Efficient District Heating in European Urban Areas

    Author : Urban Persson; Sven Werner; Louise Trygg; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; District heating; energy efficiency; distribution capital cost; heat density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation; effective width;

    Abstract : The Member States of EU27 need to accelerate the integration of energy efficient technology solutions to reach the 20% energy efficiency target set for 2020. At current pace, projections indicate that only half of expected primary energy reductions will be reached. READ MORE

  4. 2. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System

    Author : Habib Aghaali; Hans-Erik Ångström; Carlos Guardiola; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; heat transfer; heat loss; exhaust heat utilisation; waste heat recovery; turbocompound; divided exhaust period; internal combustion engine; gas exchange; pumping loss; variable valve timing; WHR; DEP; Turbo; värmeöverföring; värmeförluster; avgasvärme utnyttjande; förluster vid värmeåtervinning; turbocompound; delad avgasperiod; förbränningsmotor; gasväxling; pumpningsförlust; variabla ventiltider; WHR; DEP; Vehicle and Maritime Engineering; Farkostteknik; Energy Technology; Energiteknik;

    Abstract : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. READ MORE

  5. 3. Reduction of heat transfer and heat load in internal combustion engines

    Author : Joop Somhorst; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; efficiency; TBC; thermal barrier coating; surface roughness; engine; heat transfer; emissions; alumina; zirconia;

    Abstract : Thermal insulation of the combustion chamber in an engine has great potential to reduce fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. READ MORE

  6. 4. Modeling Diesel spray combustion using a Detailed Chemistry Approach

    Author : Jonas Edman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The rapid development of computer hardware during the past decade has contributed substantially to advances in almost all branches of science. Computer modeling is being applied to increasingly small physical scales and increasingly large domains, facilitating the generation of advanced phenomenological models and models based on first principles.

  7. 5. Processes in Optical Diesel Engines - Emissions Formation and Heat Release

    Author : Ulf Aronsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Engines; Optical Engines; Heat Release; Combustion; Emissions Formation; Mechanical Deformation;

    Abstract : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. READ MORE
